The object of this invention is toprovide an improved apparatus for'feeding vinegar stock into the vinegar-generator: 1

' Another object of this'invention is fto'make the apparatus adjustable so that it is possible to distribute the vinegar stock over a largeor small area a v These and other bjectskof this inventi'o-n will befully fillustr'at'edfin the drawing, described in the specification and pointed out in the claims at the end thereo'ff.

The tipple is formed in-t'he torn; 01. a scoop havingtwo'sidesfbottom and one end, the ;other end bein'g o nitted to allow the vinegar stools: to beidischarged from the ltipple at,

this point. ,Theshaft 5', on, which the tipple issupportedto swing inthe container passes thru the sides of the tippleand is suitably held place thereon..

The top of the container is closed: by the a cover '6 a In this coveris providedan open ing 7 im which the vinegar stock is fed from 'a suitable. reservoir into the feeding Iniechanism. For-this purp'o'se a spigot is provided on theend ofi thejhose'leading fromthe reservoir. Ihenozzle 0f this spigot into' thetipplel 'ofthe container 1'.

leads into the opening? in the cover to 'd-i rect the stream ofthe vinegar stock direct The tipplei is normally suspendecl by the shaft 5 with'itsflopen front end tilted up so that the vinegar stock flowing out of the 1 spigotnwi'll'aceumulatetherein. Asthe tipple' is being filled with vine ar "stoclrthis inclination of the tipple gradually increases until therea'r end of the bottom of the-nipple vrests on the 1 block 9 placed in the bottoIn-oi? the containerto form "a suitable support for the ti-pple-at a predetermined inclined position thereof. Any additional-liquid which is fed into the tippleafter it rests on the block 9,

tipple tothe point where the weightfof the liquid contained in the forward portion oi the tipple' gradual-1y counte'rb alances andthen ti'on of the ti-ppl'e." The" tipple will tip at the front end as soon as the Weight of the .overbalances the weight in the rearward gporliquid int he forwardportio'n 0f the tipp'le "overbal'ancesthe weight of the liquid in the rear portion of the'tipple. When this hap after it has been overbal'a'nced as above point- ,ed out, is arrested by apair of blocks 10 and llmounte'd in thebottom of the container 1. 'Under the forward endof the bottomof "the tipple a pair ofsiini lar blocks l2 and 13'a're "fastened, with which the blocks IOand 11 make contact to arrest the front" end of the tippl'eat a suitable distance from the bottom After each -dumping operation, that is; as

soon as the vinega'r'stock is drained from the tipple, it automaticallyreturns to' its norm'al inclined position, due to the fact that the tipple when empty is slightly ove-rbalanced towardthe rear end thereof, as heretofore pointed out, and when filled the tipple is. overloalanced-toward the front. 0nd hatch is then ready to be run into the tip'ple and finally dumped into the container asiabove described. This cycleofoperation repeats itself with unerrino regularity as I "vinegar, stock continues to flow into vinegar stock reservoir.

' Threadedinto thebottom of the container having the sprayer cup 15 supported on the the it p ro t 11 0 i ,1 near the "front endthereof isflthe pipe 14 p I lower end thereof. This pipe projects downwardly into the vinegargenerator and. holds the spraying cup suspended at suitable distance above the filteri'ngmaterial contained in the generator. The spraying, cup, comprises a disc-"having an annular'ch'annel e-ch n el. has a curved bottom and curved sides that.

formed in the face thereof.

converge in the center of the cup into a-cone '16. 'Theapexof the cone 16 "projects above the spraying cup. A threadedhole passes thru the center ofthe spraying cup to receive. the threaded stem 17 depending from the sleeve 18.. The stem 17 is centered Wltll riveted thereto.

between the face of the cup and the lower endofthe pipe 14. A-locknut 19 is provided to lock, the spraying cup atany desired elevati'on'on the stem 17. The sleeve 18i-sheld in place in the lower end of the pipe 14 by means of a suitable set-screw '19 which clamps the sleeve in place within the tube. j

' The spraying cup is located centrally the generatoras it is held suspended from the container by the pipe 14. Both the pipe 14 and-sprayer cup 15 are made of hard 7 rubber or anyother acid resisting material.

The sleeve 18, thread'ed'stem 17 and set screw ,for holding the sleeve 18in place within the lower end of thepipfe 14 are preferably .made up-of Monel metal which is also" acid resisting and'will stand up under theaction of vinegar; stock.

outof the opening in the bottom of'the pipe 14 without accumulating in the bottom of the container. The pipe 14 is large enough so that the liquid passing into-it will quicklydrain therefrom into the spraying cup 15.

the columnof liquid in, the pipe, ,forces the liquid down on the curved sides of the cone formed in the centerxof the cup and up the curved side of the channel formed therein,

spreading the liquid overthe surface of the filtering material by sprayingit in a thin sheet concentrically to the. spraying cup.

[The curvature of theouter wall of the. channel on. the spraying cup is designed to deflect the liquid upwardly at an angle' which will throw the liquid over a predetermined area 7 within the vinegar generator at the beginning of the spraying operation when the weight of the liquid column within the tube 14 is the" greatest. As the liquid column diminishes in height, with a corresponding 7, When the vinegar'stock is dumped into the container by means of the mechanism heretofore describedthe liquid will siphon The pressure with which the liquid drops ,onto the spraying cup, due to the height of generator as a unit. 7

reduction in the' pressure 'at gwhichlit is forced out of the end of the pipe, the liquid is sprayedagradually shorterdistance in a way that will cover the whole of the surface of thefilteringmaterial within the range' of' the'spray'that is produced by the maximum. pressure of the liquid column; Thisrange of 'the'spray can be varied by changing the location of the spraying cup .on thefend of thepipe 14. This is done by threading the cupv up or 'downfon-thethreaded stem so as to. increase or "decrease the space between'the end of the pipe 14 and the face of theflspraying cup 15. I the face of the spraying cup is'held close to the end of the pipe 14 the liquid passing out of the jpipeintothecup is forced out over a larger area than is the case when the cup is lowered on the threaded stem and the distance increased between the endf-offthe pipe 14.,and. the'face' of. the spraying cup. In this way thespraying cup can be adjusted to spray the vinegar stock ,over' a large ,or small area according to filtering area exposed'within the vinegar generator.

nism'; and spraying mechanism is thus made Thus when so I The container twith jitsduin'ping mechal up in a single unit" that can be movedand mounted as such in any-desired position on top of any vinegar generatorwiththe distributor within theflgenerator. I I a From an inspe'cti n of Figure 2 itwill be seen that the pipe 14 is enlarged at the lower end thereof to 'receivei'the sleeve .18. In
